KYOSHO Ultima 1987 JJ Replica Kit No: 30642
Most sought after World Championship buggy
‘JJ ULTIMA’ recreated in all its glory!
American Joel Johnson won his first 2WD class world title at the 2nd Electric Off-Road World Championship in England in 1987 driving a modified Kyosho ULTIMA. Also, TQ’ed this event and finished 1st and 2nd and 3rd.This became known as the ‘JJ Spec’ and was popular with its custom suspension, main chassis and front-rear shock stays that enhanced performance and styling. Only third-party conversion kits were available at the time and even then, it was extremely difficult to completely reproduce the JJ specifications. Now the ‘JJ Spec’ is honored as the 13th model in the Vintage Series to commemorate Kyosho’s 60th anniversary.

FRP shock stays flexibly absorb impact from the shock units and follow the original design in shape and color. Standard gold shocks combine with newly developed medium soft (MS) front springs.
Rear shocks are also the same gold type as on the original. Medium Hard (MH) rear springs work in combination with the MS front springs to deliver exceptional maneuverability and performance over surface gaps.
In place of the mini steering servo that was fixed with double-sided tape, the modern version of the ULTIMA uses a servo mount compatible with modern low-profile servos that are popular today. The shape of the servo saver arm has also been changed.
The front skid on the carbon chassis improves clearance over surface gaps while front caster angle setting optimizes handling characteristics.
Newly designed front wheel shaft with kingpin offset delivers improved straight line running stability as well as controlled initial steering response.
Gunmetal anodized aluminum motor guard is laser-printed with the Kyosho 60th anniversary logo, which is exclusive to the special limited-edition model.
Polycarbonate rear wing and side plates have been recreated as per the original JJ specifications. The large side plates deliver improved stability to fully recreate the style and drive feeling of the original.
